This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, glyceryl acrylate/acrylic acid copolymer.

When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

This product contains antioxidants (resveratrol) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - ascorbyl glucoside also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
